Unknown Overflow Issue - can't find answers in other threads

Hi all.

I’ve spent hours trying to solve this, including looking through old threads, but can’t figure it out. The issue started once we upgraded our nav bard, but the nav bar doesn’t seem to be causing it.

On mobile, we’re overflowing to the right, yet we can’t find any elements pushing the margin out. We’ve tried to hide-overflow on the body, but then you can’t scroll the site when published.

Can anyone help?

Here is my site Read-Only: Webflow - VIVO-Fitness

It would be helpful if you could share a published URL to the page, so inspection in a browser is possible. Using a browsers dev tools is how I quickly determine overflowing elements.
